The driver, 37-year-old Jose Luis Duran Yovis of Williams, was taking the ramp from southbound Interstate 5 to southbound Highway 113 at about 4 a.m. Friday when he allowed his Freightliner big rig to drift off the roadway, CHP Officer Bryan Konvalin said.

The Freightliner struck a light standard, knocking it to the ground, before continuing to the right where it crashed into a perimeter fence and a tree, Konvalin said in a news release. The impacts caused the big rig to jackknife and hit a propane storage tank just west of the roadway, he added.

Although the propane tank remained intact, the big rig’s fuel tanks ruptured, spilling 50 to 100 gallons of diesel fuel into the surrounding dirt area. Tow trucks and a hazardous materials crew were dispatched to the area for cleanup, which Konvalin said lasted until nearly 3 p.m.

No road closures or injuries resulted from the incident, Konvalin said.
